Table 4

Average abundances based on the coadded spectra and obtained at three effective temperature points.

Group	T _eff	log g	ξ	log ε(Ca) ^b	log ε(Fe) ^d
	(K)	(cgs)	(km s^-1)	NLTE	NLTE

TOP	6327	3.98	1.46	4.39 ± 0.61	4.98 ± 0.30
SGB	5676	3.55	1.12	4.32 ± 0.14	5.08 ± 0.19
RGB	4718	1.69	1.27	4.37 ± 0.03	5.23 ± 0.04

Δ(TOP−RGB)	1609	2.29	0.19	+ 0.02	−0.25

Notes. The average stellar parameters for the TOP/SGB/RGB stars are based on the averages from the coadded spectra with the warmest or coolest three T_eff values.

^(b)

Based on three Ca I λλ6493.9, 6499.7 and 6717.7.

^(d)

Based on five Fe I and one Fe II lines λλ6495.0, 6518.4, 6592.9, 6593.9, and 6678, and λ6516.1.
